Interface for language integration in the REPL.

Required Methods

fn prompt(&self, is_continuation: bool) -> &str

The prompt to display. is_continuation is true for multi-line input.

fn is_complete(&self, code: &str) -> bool

Check if the input is complete (e.g., all brackets are closed). If it returns false, the REPL will enter multi-line input mode.

fn handle_line(&mut self, line: &str) -> Result<HandleResult, ReplError>

Execute the given line of code.

Provided Methods

fn highlight<'a>(&self, _code: &'a str) -> Option<HighlightResult<'a>>

Get syntax highlighting for the given code.

fn get_indent(&self, _code: &str) -> usize

Get the current indentation level for the next line in multi-line mode.
